DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

With reference to FIGS. 1 and 2, an exercising device in accordance with the present invention comprises a base (10), a sliding bracket (20) and a supporting board (30). The base (10) comprises a bottom frame (11), two curved rails (13) and a guiding device (14). The bottom frame (11) is rectangular and is composed of two longitudinal side bars, a middle bar and two lateral end bars mounted between the longitudinal side bars. Multiple supporting posts (12) are mounted respectively on ends of the longitudinal side bars.

The curved rails (13) are mounted on the bottom frame (11) and are parallel to each other. In practice, the curved rails (13) are mounted on the supporting posts (12) and respectively correspond to and are parallel with the longitudinal side bars. In the first embodiment, the curved rails (13) are convex curved rails (13).

The guiding device (14) is mounted on the bottom frame (11) between the curved rails (13). In the first embodiment, the guiding device (14) comprises a guiding frame (142) and a connecting bar (34). The guiding frame (142) is inclinedly mounted on the bottom frame (11) near one end of the bottom frame (11) and has a top and an oval guiding channel (143) defined in the top of the guiding frame (142). The connecting bar (34) is attached to the bottom of the supporting board (30) and slidably extends into the oval guiding channel (143) in the guiding frame (142).

To inclinedly mount the guiding frame (142) to the bottom frame (11), two supporting columns (141) in different lengths are mounted respectively on one of the lateral end bars and the middle bar of the bottom frame (11), and the guiding frame (142) is mounted on the supporting columns (141).

The sliding bracket (20) is slidably mounted on the base (10) and comprises a cross bar (22), two side frames (21) and a driving device. The cross bar (22) has two ends. The side frames (21) are attached respectively to the ends of the cross bar (22) and are slidably and respectively attached to the curved rails (13) of the base (10).

The driving device is mounted between the side frames (21) and the curved rails (13) to drive the sliding bracket (20) to slide along the curved rails (13). In a preferred embodiment, the driving device comprises multiple rollers (23,24) and a motor (26). The rollers (23,24) are rotatably attached to the side frames (21) at sides facing to each other and are arranged in pairs. In an alternative embodiment, the rollers (23,24) are rotatably attached to the side frames (21) at sides opposite to each other. The rollers (23,24) of each pair abut respectively with a top and a bottom of one of the curved rails (13). The motor (26) is attached to one of the curved rails (13) and is connected to and drives one of the rollers (24). When the motor (26) is switched on, the roller (24) connected to the motor (26) will be rotated, such that the sliding bracket (20) will be driven to slide along the curved rails (13).

The supporting board (30) is rotatably mounted on the sliding bracket (20) and is connected to the guiding device (14) on the base (10) to make the support board (30) being mounted on the sliding bracket (20) in a swinging manner. To rotatably mount the supporting board (30) on the sliding bracket (20), a sleeve (27) is mounted on the cross bar (22) of the sliding bracket (20), and a mounting post (33) is mounted on the bottom of the supporting board (30) and rotatably extends into the sleeve (27) on the cross bar (22). In addition, the supporting board (30) may further comprise an I-shaped post holder (32) attached to the bottom of the supporting board (30), and the mounting post (33) and the connecting bar (34) are respectively attached to a middle and one end of the post holder (32).

With further reference to FIG. 3, when the motor (26) is switched on and the sliding bracket (20) move along the curved rails (13), the supporting board (30) will move with the sliding bracket (20) along the curved rails (13) in a curved track. With the curved movement of the supporting board (30), the connecting bar (34) will move along the oval guiding channel (143) in the inclined guiding frame (142). With the inclined arrangement of the guiding frame (142) and the oval guiding channel (143), the supporting board (30) will swing during the movement. With the curved movement and swinging motion of the supporting board (30), muscles of hands, legs and waist of a user can be trained when the user intents to keep balance on the swinging supporting board (30). Accordingly, the exercising device in accordance with the present invention can simulate a skateboarding action to provide a versatile and exciting exercising effect to a user who stands on the supporting board (30).

With reference to FIG. 4, in a second embodiment, the curved rails (13′) are concave curved rails (13′). The length of the sleeve (27′) of the sliding bracket (20′) is prolonged to keep the supporting board (30) bumping with the curved rails (13′).

With reference to FIG. 5, in a third embodiment, the guiding device (15) comprises a guiding bar (151), a lever (152), a guiding tube (153) and a connecting bar (34). The guiding bar (151) is inclinedly mounted on the bottom frame (11) and has a top. The lever (152) is rotatably attached to the top of the guiding bar (151) and has a free end. The guiding tube (153) is secured on the free end of the lever (152). The connecting bar (34) is attached to the bottom of the supporting board (30) and rotatably extends into the guiding tube (153).

When the supporting board (30) moves with the sliding bracket (20) along the curved rails (13) in a curved track, the connecting bar (32) will drive the lever (152) to rotate relative to the inclined supporting bar (151). With such a guiding device (15), the supporting board (30) will be swung on the sliding bracket (20).

With reference to FIG. 6, the guiding device (15′) comprising an inclined guiding bar (151′), a lever (152′) and a guiding tub (153′) can be applied on an exercising device having a base (10′) with concave curved rails (13′). In the fourth embodiment of the exercising device in accordance with the present invention, the length of the sleeve (27′) on the cross bar (22) of the sliding bracket (20′) is prolonged to keep the supporting board (30) from bumping with the curved rails (13′).
